Abstract
PT. XYZ is engaged in furniture manufacturing that produces aluminum woven chairs with a make to order (MTO) system. Changes in the number of product requests cause the distribution of workloads between work stations to become unbalanced so that the company's production targets have not been achieved optimally. This study was conducted to obtain standard work time and evaluate the level of labor workload through the application of the Work Load Analysis (WLA) method, as well as to compare alternative labor costs in the production process of the Hampton DAC type aluminum woven chair. The Stopwatch Time Study method was applied to determine the standard time for each work activity, while the Work Load Analysis (WLA) method was used to analyze the optimal labor requirements based on the level of workload that occurs in the field. Based on the results of the study, the weaving process is the activity with the largest standard time, which reaches 52.63 minutes for each product unit. Based on the WLA analysis, the optimal labor requirement is 36 workers, while the company's actual workforce is 27 workers, so additional labor is needed. The results of the cost comparison show that the use of casual daily labor is the most efficient alternative compared to overtime and the addition of permanent workers.
